I ADJUSTABPEDRAINBQAKDFOR T0 dllwhom it mag concern.

Be it known that 1', MAX KLUGE, a citizen of the United States, residing at Billings, in the county of Yellowstone and State ofMontana, have invented new and useful Improvements in Adjustable Drainboards for Sinks, of which the following is-a specifica= tion. I 1

The invention relates to drain boards and more particularly to the class of adjustable or movable drain boardsfor sinks.

- The primary object of the invention is the provision-of a drain board wherein the same is hung upon a kitchen sink so that it can be lowered when not in use tobe out of the way, and may be readily and easily raised to operative position for use to permit the draining of articles placed thereon as usual.

Another object of the invention is the provision of a drain board cf' thischaracter wherein the clamps for fastening the same to the sink are of novel form so that thesaid board can be fastened to sinks now in use, either of the straight edge orrounded edge type, and when the said board is raised it will be firmly locked in such position for use.

A further object of the invention is the provision of a drain board ofthis character wherein the meansfor locking the board in raised position is of novel form and can be readily unlatched to permit the lowering of the board when not in use. v

A still further object of the invention is the provision of a dra'in board of this character which is simple in construction, reliable and eflicient in use, strong, durable, andinexpensive in manufacture.

With these and other objects in view, the invention consists in the construction, combination and arrangement of parts as will be hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereunto appended.

In the drawings :-Figure l is a front elevation of a sink showing the drain. board constructed in accordance with the invention applied and in position for use. Fig. 2 is a similar view showing the board in lowered position when not in use. Fig. 3 is an enlarged vertical transverse sectional. view through the drain board, showing in eleva tion the detail mounting thereof on the end of the sink. Fig. 4: is a sectional view on the line H of Fig. 3. Fig. 5 is a sectional View on the line 55 of Fig. 3. Fig. 6 is a side elevation of one of the clutch sleeves. Fig.

Similar reference characters indicate corresponding parts throughout the. several views in the drawings. i

" Referring tothe drawings in detail, A designates-generally: a sink having the usual roundededge. B,-to1which is connected tl e drain board hereinafter fully described.

. The drain bo-ard comprises shelf section 10 formed with a corrugated drain portion 11 andwith a curved end 12 which is adapted to overlap the edge 13' of the sink A when the board is in raised position for use so thatv water will-flow in the direction of and into the sink from. the said board during its use; Secured to the under face of the shelf section 10 constituting the drain board, are spaced bearings 13 in which is mounted a pivot rod 14 for the sink clamps C and D,

respectively, as will be hereinafter fullydescribed. 1

The clamp C colnprises'a'curved jaw 15 formed with a clutchsleeve 16, and a clamp screw bearing 17 in which is threaded a clamp screw 18 whichcooperates with the jaw 15 for the fastening of. the clamp to centrally theretlirough the pivot rod 14, and is formedwith a segmental slot 19 and an arcuate groove 20 opening thereinto, the latter being adapted to receive the bill 21 of ahook likelug 22 formed ona companion clutch sleeve 23 adapted to cooperate with the clutch sleeve 16 and surrounding the pivot rod 14, the clutch sleeve 23 being fitted with a binding screw 24 so that it may be adjustably fixed -on the pivot rod 14, while the clutch sleeve is loosely mounted upon the latter. The lug 22 on the sleeve 23 works in the slot 19 and is adapted to limit the swinging movement of the shelf section 10 when being raised or lowered relative to the sink A by the clamps C and D, and this shelf section 10 is locked in raised position in a manner presently described.

Mounted in a suitable guideway in the companion clutch sleeve 23 is a spring-held latch bolt 25 which is adapted'to engage in a socket 26 formedin the clutch sleeve 16 when the shelf section 10 has been raised so as to lock it in such position, the bolt 25 being formed with a handle 27 at right angles thereto so that it may be retracted the sink. Ihe'cl-utch sleeve 16 has passed against" the resistance of the spring 28 "acting thereon to unlatch the clutch sleeve23 from the sleeve 16 whereby the shelf section 10 can be lowered when not in use.

The sink clamp D comprises a jaw "29 formed with an eye 30 through which is" passed the pivot ro d ll and a clamp screw bearing 31 in which is threaded a clamp screw 32 which cooperates with the jaw 29 for the fasteningof thelclamp D to the, sink A. The clampsC and D support the pivot rod 14, which also swingingly supports the.

, clamping end a self-adjusting bearing disk 35so that the clamps can be readily fas-.

tened to the sink E with the straight edge.

The pivot rod 14 at one end is formed with a squared portion 36 which engages a corre- ,spondingly shaped opening in the bearing 13 therefor so as to prevent the turning of the pivot rod 14 in the bearings connecting it to the shelf section.

To give the drain board the right angle or the necessary slope when in use, after fastening the two clamps to the sink it is necessary to turn the clutch sleeve 23 so that it will lock itself through the spring held bolt 24 and thereafter raise the drain board toright angle and fasten the clutch sleeve to pivot rod 14 through binding screw 24.

From the foregoing description, taken in connection with the accompanying drawings, the construction and manner of use of the device will be clearly understood, and

' therefore a more extended explanation has been omitted.

What is claimedis: 1. The combination with a drain board, of hangers fixed to its under side, a shaft mounted in the hangers, a curved jaw a formed with a clutch sleeve receiving the shaft and also having a clamp screw hearing, a clamp screw threaded in the bearing and cooperative with the jaw, a companion clutch sleeve adjustably fixed on the shaft, the said first-named sleeve having a peripheral arcuate shaped slot, a hook-like lug on the last-named clutch sleeve and engageable in the slot to limit the relative movement of the clutch sleeve, and means in one clutch sleeve and engageable in the other clutch sleeve to lock the same in adjusted position.

2. The combination with a drain board, of hangers fixed to its under side, a shaft mounted in the hangers, a curved jaw 3 formed with a clutch sleeve receiving the shaft and also havinga clamp screw bearing, a clamp screw threaded in the bearing and cooperative with the jaw, a companion clutch sleeve adjustably fixed on the shaft, the said first-named sleeve having a peripheral arcuate shaped slot, a hook-like lug on thelast-named clutch sleeve and engageable in the slot to limit the relative move ment of the clutch sleeve, and a spring-held,

bolt in one clutch sleeve and engageable with the other clutch sleeve to lock the same together and having a handle.

In testimony whereof I afiix my signature in presence of two witnesses.
